When throwing when angling, fishing line to be led arm 40 be turned to the unwrapping wire state, the forefinger with the hand of holding fishing rod under this state hauls fishing line and the fishing rod of jettisoninging.Like this, fishing line can angle unwrapping wire swimmingly under the group action of gravity.Under this state during to take-up direction turning handle assembly 1; Rotor 3 rotates to the take-up direction under the effect of rotor driven mechanism 5; And spool 4 also under the effect of swing mechanism 6 forwards, backwards direction move back and forth; And fishing line leads arm 40 and restores to the take-up position through the not shown effect of leading the arm switching mechanism, and fishing line is wound on the spool 4.
In the swing mechanism with said structure 6, because ending the connecting portion 30 of the driven gear 23 on the gear fastener 27 of grooved cam 21, card has grooving 30a, this grooving 30a adopts machining process and forms.So grooving 30a is blocked accurately only on gear fastener 27.Therefore, the present invention can adopt that on rotation direction, to produce pine between simple machining process control grooved cam 21 and the driven gear 23 spacious.
[the 1st modified example]
In above-mentioned the 1st embodiment, not only on rearwardly projecting lug boss 31, be formed with the grooving 30a of connecting portion 30, and grooving 30a also forms the state that crosses lug boss 31.In the described gear installation structure 120 of the 1st modified example, as shown in Figure 7, with respect to the grooved cam that is same as the structure in the 1st embodiment 21, lug boss 31 is not set and formation grooving 130a.
Like Fig. 7 and shown in Figure 8, the described driven gear 123 of the 1st modified example has connecting portion 130, and this connecting portion 130 is recessed to be formed on the rear end face of driven gear 123.Connecting portion 130 has grooving 130a, the recessed formation Long Circle of this grooving 130a.The rear end face of driven gear 123 is not crossed at the both ends of this grooving 130a and to be with the width W of grooving 130a that diameter forms circular-arc.Therefore, can use with the width of grooving 130a and easily form this grooving 130a as the slotting cutter of diameter.
Driven gear 123 with said structure can be installed on the grooved cam 21 that is same as in the 1st embodiment.Identical in the diameter D2 that the width W of grooving 130a and axle center align portion 129 and the 1st embodiment.
Here, because forming, grooving 130a do not cross the state of rear end face, so, when being used for forming the machining of grooving, be difficult to occur making the gear teeth to produce the problem of damaged grade even lug boss is not set yet.
[the 2nd modified example]
In the 1st embodiment and the 1st modified example, the axle center aligns portion 29 and aligns the width of the diameter of portion 129 less than grooving 30a and grooving 130a with the axle center.But in the described gear installation structure 220 of the 2nd modified example, like Figure 10 and shown in Figure 11, the width W of grooving 230a aligns the diameter D2 of portion 229 less than the axle center.Therefore grooving 230a mid portion in the longitudinal direction forms circular-arc and links to each other with inner peripheral surface that the axle center aligns portion 229.
In addition, as shown in Figure 9, the graft union 225c of grooved cam 221 and the diameter of gear support portion 226, big than in the 1st embodiment and the 1st modified example.But the interval of a pair of line part 227b little than in the 1st embodiment and the 1st modified example.So a pair of line part 227b is by sagging in graft union 225c and the gear support portion 226.Therefore the both ends card except mid portion of grooving 230a ends on a pair of line part 227b.Thereby can be by the arc sections 227a supporting driven gear 223 of gear support portion 226 and gear fastener 227.So driven gear 223 is difficult on fore-and-aft direction, produce.
[the 2nd embodiment]
In the 1st embodiment, the diameter of the gear fastener 27 of grooved cam 21 is greater than the diameter of gear support portion 26.But in the described gear installation structure 320 of the 2nd embodiment, shown in figure 12, the diameter of the arc sections of the gear fastener 327 of grooved cam 321 is identical with the diameter D1 of gear support portion 326.Therefore, the length L of the line part 327b of gear fastener 327 is less than the diameter D1 of gear support portion 326.
In addition, in driven gear 323, like Figure 13 and shown in Figure 14, lug boss 331 is given prominence to forward and is formed from the front end face (example of the 1st end face) of driven gear 323.The grooving 330a of connecting portion 330 is formed on the lug boss 331, and the width W of grooving 330a aligns the diameter D2 of portion 329 less than the axle center.The axle center aligns portion 329 and is formed on the whole length of driven gear 323, and it forms length is only to form the outstanding a little length of part to lug boss 331.
Have in the described gear installation structure 320 of the 2nd embodiment of said structure, owing to adopt machining process to form grooving 330a, on rotation direction, to produce pine between driven gear 323 and the grooved cam 321 spacious so can control.In addition, because grooved cam 321 begins diminishing gradually to the diameter of both end sides from axle body 325,, the machining of grooved cam 321 carries out easily so becoming.
